Hi my name is Don Bishop and this is my “Deal” Today... Basically, anything that interest me. Music, Computers, Software, Apps, Linux OS's - Distros, Space, Science, Auto's, Trucks, 4x4's, Motorcycles and other slightly interesting info that I find on the Web. There may, or may not be, any correlation between my Posts. Just whatever interests me at the time. I hope someone out there finds some of this interesting too!:)

Emotiv System's only current product is the Emotiv EPOC, a $300 peripheral for gaming on Windows PCs. Emotiv Systems claims the headset will make it possible for games to be controlled and influenced by the player's mind, and facial expressions. It connects wirelessly with the PC, and may in the future work on other game platforms such as consoles. The Epoc was designed by Emotiv Systems in conjunction with the Sydney based Industrial Design consultancy 4design.[7][8]

The EPOC has 14 electrodes[9][10] (compared to the 19 electrodes of a standard medical EEG, and the 3 of OCZ'sNIA features and a multiple of NeuroSky's single electrode). It also has a two-axis gyro for measuring head rotation.

The headset must first be trained to recognize what kind of thought pattern equates to a certain action. It can measure four categories of inputs:[11]

Conscious thoughts (Cognitiv suite): Imagining 12 kinds of movement- those were in the demo application 6 directions (left, right, up, down, forward, and "zoom") and 6 rotations ([anti-]clockwise rotation, turn left and right, and sway backward and forward)- plus 1 other visualization ("disappear") that can be detected in µ rhythms. While the current driver may only be able to listen for any 4 of these at a time, the degrees of freedom are larger than a joystick's 2 df. Ideomotor responses ("I found myself inadvertently tightening my stomach muscles, or raising an eyebrow when I tried to make the box float. The Emotiv guy used his hands to try and cue himself to think the same way every time." (emphasis added)[12]) or the much stronger EMG currents aside, these thought commands effectively become hotkeys. Videos of Emotiv employees playing "The Game" show a high degree of difficulty in adapting and thinking right even as experienced users. Users can train the 13 visualizations to totally different thoughts than the ones specified, but detection ability will be worse.[citation needed] Due to the complex detection algorithms involved, there is a slight lag in detecting thoughts.[13] However, the technology may still be useful in a support role like calling up a minimap or radar in a FPS game.

Emotions (Affectiv suite): "Excitement", "Engagement/Boredom", "Meditation", and "Frustration" can currently be measured. Emotiv admits that the names may not perfectly reflect exactly what the emotion is, and says that they may be renamed before market launch.

Facial expressions (Expressiv suite): Individual eyelid and eyebrow positions, eye position in the horizontal plane, smiling, laughing, clenching, and smirking can currently be detected. Other expressions may be added prior to release. The expressions are detected by the EEG sensors picking up signals to facial muscles, rather than by reading brainwaves. Unlike reading mental activity, these detections are very fast (10ms)[14] conveying a decisive advantage and rendering them suitable for fast paced games in the FPS genre.

Head rotation: The angular velocity of one's head can be measured in the yaw and pitch (but not roll) directions. This is detected by gyros, and isn't related to the EEG features.

For compatibility with non-compliant software EmoKey would be provided in order to bind commands to keys or combinations thereof transforming the device into an HID.

EPOC can be used to get EEG data (the raw electricity measurements), with the Python Emokit[15] without the need for EPOC's proprietary software, Research, Research Plus or Enterprise Plus SDK licenses ($750, $2,500 and $7,500 respectively).[16]

The Emotiv EPOC will ship with a game by Demiurge Studios, previously called "The Game", built on the Unreal engine. Videos of portions of the game have been shown at conferences and in media interviews. The game involves a first person view of the user walking around a virtual environment, with many different activities at different locations. The sky changes color according to the mood of the player. Demonstrated activities in the game include pushing and rotating giant stone structures into the shape of stone henge, then raising a temple from below the ground; levitating a large rock and some smaller ones; repairing a bridge; bending a tree; and scaring away glowing spirits with scary facial expressions.

The EPOC also includes "EmoKey" software used to emulate keystrokes based on combinations of thoughts, feelings, and facial expressions. Any EPOC detection can be paired with keystrokes or string of keystrokes through a simple user interface by the end user. Future versions will also emulate the mouse based on the gyros. This software allows most existing games, instant messaging programs, and other software to be controlled with the headset.

There is also a planned web site known as "Emortal", for listening to music, viewing photos, and other activities, modified based on what the user is thinking and feeling.

Another product is the Emotiv Control Panel, also seen in many videos, which allows users to train the various thoughts, such as "push" and "disappear", and test them on a floating, bobbing, cube. It also allows users to view their emotional state, such as "excitement", on a graph. It has a 2D blue avatar that allows the user to view their own facial expressions, and adjust the sensitivity of those detections.

A free SDK (called SDK Lite) is also available for download from the Emotiv website.[18] It includes software to emulate the Emotiv EPOC for developers who do not have one of the (beta version) headsets. A SDK interface will give Linux users[citation needed] a more powerful control for recoding and modification of the Emotiv head set for other game consoles and programs.

Emokit is an open-source Python library for reading out sensor data from the EPOC by Cody Brocious. It was built by reverse-engineering the encrypted protocol.[15]

At the Game Developers Conference 2008, in San Francisco an Emotiv headset was among the new video game input devices there. The demo played with the Emotiv was a puzzle where the player rebuilds Stonehenge. To do so, the wearer did hand motions such as pushing and pulling to restore Stonehenge.[19]

The field of consumer BCI has three primary players, NeuroSky, Emotiv, and OCZ industries. The Emotiv EPOC has significantly more electrodes than its competitors and is not considerably more expensive, but is the only commercial EEG unit to still use wet sensor technology.

About Me

Hi I'm Don,
I write, sing and record songs of my own and I like doing this very much. My music is on my web site. My first album is called DonSongs and my second one is called Living Beings - Climate Control. You can Download and listen and save all our songs on my web site at DonSongs.com and it's completely free. My favorite hobby now is computers. I like to fix old Computers and make them usable again with different Linux Operating Systems or just fix up messed up WindBlows systems;). I really like researching interesting things on the Internet. I read allot about many things, Technical things on computers and the Internet, interesting discoveries in science, new technology, local and world news and just what ever strikes me as interesting. I am very handy and good with tools, fixing and making things. I like to help my friends with their projects when I can. I love Hot Rods and use to do Motor Swaps and put Big Block Chevy Motors where 6 cylinders once were. I love 4 Wheeling and Dirt Bike Riding But I don't have a motorcycle any more. I still really like 4 Wheeling in my 1976 Chevy Blazer, when I can afford the Gas and cost of Broken Parts that is...!!!:O
Don
